Frosty Whip From Australia

hi! has anyone used this?what is the ratio?i bought a repacked one, i just read the instructions from the original package at the shop where i bought it, as to the ratio, which says 1:1..but it's too watery after a minute or 2 of whipping it..i'm planning of putting more powder..but perhaps, anyone from here has used it before & would be nice enough to share the ratio...would appreciate it very much...thanks in advance
